Default dyno'd-silver can 540j after long break-in

These are the dyno results from a freshly broken-in tamiya 540j silver can motor. I am posting this hoping for feedback from anyone. Tell me your methods and your results. I don't know if these numbers are worth the time spent on break-in or not. Let me know if anyone is interested in my method. Anyway here are the numbers I acquired with a standard motor rpm tester with no load.

BTW- any questions or comments will be helpful. This is the first time I have dynoed a tamiya 540j silver can.

Looks like an average, run of the mill, broken-in 540J.

Thats not a dyno run. its just a rpm check. And it does not neccessary tell anything about power.

Actually, I would say somewhat below average for simply broken in. We're seeing 13,100 @ five volts for most current run soft brush motors and about 13,500+ @ five volts for the newer carbon silver brush motors (brushes have 'CS' engraved on them).

Our full race motors are currently pulling about 20K at five volts with a power number of 42-45 on a Facts Machine dyno. So, something to shoot for.

Doc was referring to his Red Dot motors which he builds and has for sale. Well worth the price. As a disclaimer, I have no interest in the Red Dots, but am an admirer of Doc and his products.

Magnet zapping to advance timing or 10amp load motor breakin (to fuse the windings) will help get the rpms up. Some also break the washers at the ends of the armature.

I thought the whole deal of silver can racing wasnt to cheat... ie advancing the timing. Its a silver can for a reason...

If you know what you are doing, you can achieve what may seem like spectacular results, without advancing the timing. Interesting how people bandy around the term "cheating", when they really mean "if your motor is faster than mine, you must be cheating". I for one am sick and tired of it.

If you've got a slow motor, learn how to make it faster. If you can't do that, buy a Red DOT or find someone who knows how to do it and use one of his. All this "cheating" talk isn't very constructive. Word of warning tho, learning how can be a time consuming and expensive proposition.
